Split with regular expression

Question

How can i split string with char that is not part of the in parenthesis string

Exemple :

"(ab);(cd)" split with (;) ==> (ab) and (cd)

"(ab;cd);(abcd)" split with (;) ==> (ab;cd) and (abcd)

I can't find the regular expression solution for this thank you for your help

Answer 1

@"(?<=\));(?=\()" also works:

string str = "(ab;cd);(abcd)";

string[] arr = Regex.Split(str, @"(?<=\));(?=\()");

foreach (string str in arr)
    Console.WriteLine(str); 

// (ab;cd)
// (abcd)

Answer 2

Try:

Regex.Split(s, @"(;(?!(\w*\))))")
